How long should I work out when just starting?

In brief:
Workout Rules

When first starting anything, begin slowly and work up.

If you are over 40 and have any chronic disease, speak with your physician about stress testing. Otherwise, the goal is to get moving. Start with walking 15minutes/day to up to 30 minutes. Once you can do that, up the speed. And as you get better you can run (or whatever else) and add weights.
